Paul...MSDtold me that the 7AL2 ignition was a multi spark C.D. system
throught the entire RPM range . I wonder if LYNN HANOVER  ever took apart a
7AL2 and checked out its functioning.I don't know if they are available but a
real interesting plug to use in conjunction with a C.D. for antifouling would
want to have a tip made of iridium which happens to be the best antifouling
agent around.  But then again , all this begs for experimentation so we
really should use an an ancient , massive electrode as well as failure prone
magneto fossils as the gentleman suggested.
